So I'm pretty new to hackaday (browsed a lot of the articles for years, just never made an account), and to the whole "hacker culture" so I apologize for any faux pas I've committed.

I've been working on this project for about a year off and on, along with my other quantum projects, so everything is pretty disorganized at the moment.

The published image of the device was from our first prototype, I was going to do a whole write-up on how to build it with step-by-step instructions but I kinda lost the time.

I've since done a little more work on the hardware side, added an STM32 microcontroller with USB connection, 1 gigabyte of general storage, found a nice case to put it in, and then made this pretty cool (it sucks I know) 3d animation of it:

I'm thinking this would make a good crypto wallet, and it's looking like we're going to have a halfway decent product :) I have to order the boards and test them, getting all those components to fit in such a small area was a challenge and I'm a little worried about the "hacks" I had to do to get everything to fit, next major step would be developing the software/firmware to go with it, Linux shouldn't be a problem but I'm dreading the thought of having to write code for windows, haven't used that OS for years.

One of the things I'm debating is whether I should try to open up some of the microcontroller functionality, I've got a little room left to add a few extra vias you can solder to (and SWDIO with Trace is already available), but... I also get the feeling it'd be easier to just make a development board and/or a breakout board with the RNG circuit.
